Suffolk Defender Posted January 17, 2016 Share Posted January 17, 2016 Hi all, I have been look around the forum to try avoid duplicate posting , but still feel the need to post. The wipers on my Defender behave erratic in that sometimes the position of the wipers when in motion is normal and around 50% of the time the wipers arms run to far from the the usual normal position. To the extreme of marking the seal around the wind screen! Does this symptom point to something obvious or is it a case of taking the arms off and investigating the area for worn parts?

western Posted January 17, 2016 Share Posted January 17, 2016 probably wear on gear/cable. they wiper motor gear could be a 105 or 115 degree version, there are others for these lucas 14w motors -- http://www.s-v-c.co.uk/product/14w-wiper-drive-gear/ see the drop menu to see the options on degrees. this http://forums.lr4x4.com/index.php?showtopic=9010&st=0&gopid=96351entry96351 shows how to change the gear.

Suffolk Defender Posted January 17, 2016 Author Share Posted January 17, 2016 Thanks for the info! From looking at the "how to" post and the photos i will have to take it apart to see which degree i need to order. Quote Link to comment Share on other sites More sharing options...
Snagger Posted January 18, 2016 Share Posted January 18, 2016 I had the same problem with new spindle boxes, cable and arms. Perhaps there was a little slack in the old motor and gear box unit, but it only became an issue over 40mph with a wet screen. In the end, I bonded rubber blocks tot he screen frame to inhibit the blades. Far from perfect, but it stopped the blades tearing from repeated over-run.

Suffolk Defender Posted January 19, 2016 Author Share Posted January 19, 2016 Ok so had some time just now to take the motor off and removed the cover to show the degree version. Its a 115 degree. However, i did notice the spindles look a little worn... it maybe that. Looking at pics of new ones they make mine look a tad worn!! O/S Spindle N/S Spindle New Spindle I think i need new Spindle boxes... Melv Quote Link to comment Share on other sites More sharing options...
steve200TDi Posted January 19, 2016 Share Posted January 19, 2016 Those splined bits are held on with a grub screw, so you can just buy new adapters, like these: http://www.ebay.co.uk/itm/LAND-ROVER-DEFENDER-90-110-130-WIPER-SPINDLE-ADAPTOR-STC987-/271004994753?fits=Model%3ADefender&hash=item3f19280cc1:g:o5MAAOSwI~VTyPEl But you may still need new spindles if you deem them to worn....

Suffolk Defender Posted January 19, 2016 Author Share Posted January 19, 2016 Thanks Steve thats good to know i can buy them separate. I will change the gear as advised above and then see how things go. melv Quote Link to comment Share on other sites More sharing options...
Suffolk Defender Posted January 19, 2016 Author Share Posted January 19, 2016 I should have mentioned that i also get a click from time to time when the wipers are on. This sounds as though it comes from the wiper/ spindle area but may need more investigation. Quote Link to comment Share on other sites More sharing options...
Snagger Posted January 20, 2016 Share Posted January 20, 2016 The gear on the spindle is just a piece of stamped steel sheet with an interference fit onto the shaft. Over time, that fit may slacken and allow movement between gear and spindle, causing the click. It could also be a loose adaptor on the outside needing its grub screw tightening.

Suffolk Defender Posted January 25, 2016 Author Share Posted January 25, 2016 So the issue is still there! Changed the wiper motor gear as above and it rained the other day, went for a drive and boom the wipers go off track together. Its interesting that they both go off track together and then back to normal together. I don't think this issue is due to the spindle bit that the wiper slides onto being loose as why would both wipers over run together?

Snagger Posted January 26, 2016 Share Posted January 26, 2016 Same as mine. I was hoping to find a gear wheel for inside the motor with a smaller throw (they have different numbers representing the arc they move the arms through, the smaller degree numbers having a spigot closer to the wheel centre). The thing is, I have replaced everything in my system except the motor and gear box, which has very little wear, so it is the correct original spec, and the new cable, spindles and arms are all genuine. Go figure... Quote Link to comment Share on other sites More sharing options...
Suffolk Defender Posted January 26, 2016 Author Share Posted January 26, 2016 oh that doesnt sound very promising. I guess putting a smaller degree gear would help when its at fault but the viewable area when it is working would be smaller. I wouldn't mind but its knackering my seal around the screen and the wiper blades too! knackered seal = water down the back of the dash!
